' FRONT GUARD FOR AUTOMOBILES.

Application filed May 23, 1925. Serial No. `32,305.

- vices for automobiles and other motor vehicles such as are commonly mounted on the front en'd of the vehicle frame and are designed to protect the radiator, lamps and other fragile parts from injury in the event kof collision with another vehicle or stationary objects.

The device of my present invention h as been designed more particularly as a radiator guard or fender adapted for use on automobiles employing a spacing bar or rod between the forward ends of the side frame bars of the chassis frame and forwardlyof the front plane of the radiator.

Among the objects ofthe invention are,

to provide improved mounting and attachingmeans for the fender grid which will permit the latter to be made of a width substantially equal to the full space between the forward ends of the side frame bars. of

3o the chassis; to provide improved mounting and attaching means which will permit the fender grid'to be adjusted at different .distances froml the vertical plane of the front `of the radiator; to provide a simple and easily applied grid supporting means that may be readily mounted on the forward spacing bar of the chassis frame; and, generally, to provide a. very simple,eli`icient and inexpensive radiator guard or fender,

40 well adapted to fully protect the fragile honey-comb structure of the radiator froml injury through collision. A Other objects and attendant advantages of the invention will be apparent to persons skilled inthe art from the subjoined description, taken in connection with the accompanying drawing wherein I have illustrated one simple and practical embodiment of the invention, and in which- .'f

mobile equipped with my improved radia- `tor guard or fender;

Fig. .2 is a. side elevation, viewed from Fig. 1 is a front elevation ofan autothe right of Fig. 1, and in vertical section through the radiator guard;

Fig. 3 is an enlarged rear elevation of one of the supporting arms of the guard, partly in section on the line 3 3 of Fig. 2;

Fig.I .4 is a vertical section through the trunnion on the upper end of the supporting army and its clamp,'taken on the line 4.-4: of Fig. 3; and

Fig. 5 is an enlarged longitudinal sectionv in the plane of one of the tie-rods of the fender frame, showing one of the spacing spools between adjacent spring fender bars.

The grid structure of the guard or fender is substantially identical with that disclosed in an earlier application filed by me onthe 28th day ofMarch, 1925,"Serial No. 18,963, and comprises the following-parts. 10 des- I ignates'each of a' pairof flat-vertical side bars, which are connected at top and bottom by horizontal tie-rods 11 passing therethrough and secured by nuts 12 and washers- 13 (Fig. l5). Mounted and supportedupon the upper and lower tie-rods 11 are a plurality offuniformly spaced vertically extending spring fender bars 14, preferably taking substantiallythe form best Ishown in Fig. 2, wherein it will be seen that the bars are slightly bowed forwardly throughout the greater part of their length and'terminate in upper and lower rearwardly bent loop portions 15 and 16, the ends of which are curled around'the tie-rods 11, as clearly shown at 17 in Figs. 2 and. These spring vfender bars are rigidly spaced by means of spacing sleeves 18,mounted.onthe tie-rodsA 11 between adjacent fender bars, all as clearly shown' in Fig, l

19 designates the usual side frame bars of an automobile chassis, and 20 aconventional form of radiator located just in ad vance of the usual engine lhood or bonnet 21 22- designates a tubular'rod that extends between and spacesthe forward ends of the frame bars 19in numerous makes of automobiles. In my present invention, this rod is utilized as a supportl for the radiator guard or fender v`through the following described mounting and 'supporting means.

23 designates eachgof a pair of reversely facing and mating. 'arms,g'each off-which is formed on its upler end with inwardly exten and longitudinally an integral ioo los

toothed or serrated trunnion 24, and on its lower end with an approximately semi-circular seat 25 of a curvature to fit the curvature of the spacing rod 22. On either side of the seat 25 are apertured ears or lugs 26. 27 designates a clamp block formed on its upper side with a central seat 28 of a curvature to fit the curvature of the tubular rod 22. The opposite sides ofthe clamp block 27 are apertured in line with the apertures of the ears or lugs .26 to receive clamp bolts 29, by, which the arms 23 are strongly and rigidly clamped on the spacing rod 22. Set screws 30 threaded through cen' tral openings 31 (Fig. 3) lin the clamp blocks 27 bite into the rod 22y and prevent swinging movement of the arms 23.

Strongly attached to the inner side of each of the vertical side members 10 of the fender grid as by bolts 32 is the channelled base 33 of one member 34 of an internally toothed trunnion grip' or clamp, the other member- 35 of which, is secured thereto by bolts 36. The mating members 34 and 35 of the clamp are formed with internally toothed half bearings 34 and 35 respectively that receive between them the trunnion 24 of the arm 23; the teeth of the clamps and trunnion interfitting, whereby the clamp is securely locked on the trunnion against relative turning movement thereon. However, byV backing out the bolts 36 sufficiently to disengage the co-operating teeth ofthe clamp and the trunnion, the position of the clamp around the trunnion may be shifted.

Through the means last described the fender grid is wholly supported at two points onand from the spacing rod 22. By reason of the fact that the supporting arms 23 lie inwardly'of the vertical side members of the fender grid, as clearly shown in-Fig. 1,'it is possible to make the fender grid wide enough to substantially fill the space between the chassis frame members 19, and thus afford a complete covering and protec tion 'for the front of the radiator. .This

. construction also leaves the forwardly pro-v jecting ends of the chassis'frame bars 19 free and unobstructed for the attachment thereto of the carrying arms of a bumper. If it is desired to adjust the fender frame close-r to or farther from the radiator, this may readily be done by`loo'sening the set screws 30- provides a simple, neat and efficient protector or guard for the entire front of the radiator.

l Vclaim-- f 1. The combination with the side fram bars of an automobile chassis, and a rod connecting and spacing the forward end portions thereof, of a substantially rectangular automobile fender grid, and a pair of rigid supporting arms attached at their upper ends to the side frame members of said grid and at their lower ends nonrotatably mounted on said rod.v

2. The combination with the side frame bars of an automobile chassis, anda rod connecting and spacing the forward end portions thereof, of a substantially rectangular automobile fender grid of a width approximately equal to the distance between said frame bars, and a pair of rigid supporting arms attached at their upper ends to, and disposed inwardly of, the side frame members of said grid and at their lower ends nonrotatably mounted on said rod.

.3. The combination with the side frame bars of an automobile chassis, and a rod connecting and spacing the forward end portions thereof, of a substantially rectangular automobile fender grid, a pair of rigid upstanding supporting arms non-rotatably mounted at their lower ends on said rod and formed on their upper ends with laterally members of said grid to said trunnions.

5. The combination with they side frame bars of an automobile chassis, and a rod connecting and spacing the forward end por# tions thereof, of a substantially rectangular automobile fender grid of a-width approximately equal to the distance between saidY frame bars, a pair of rigid upstanding supporting arms clamped at their lower ends on said rod by means permitting'adjustment of said armsraround said rod and formed on their upper ends with outwardly extending longitudinally toothed trunnions, and interv nally toothed clamps mounted on said trun-` nions and themselves attached to and supported by the side frame members of said grid. i r
